Problems solved by technology

For the bitter and astringent taste, it is mainly prepared by adding sweeteners in the later stage. However, there has been no technology that is safer, simpler, and easier to apply in the factory for the problem of low bioavailability of active ingredients in tea beverage products.
However, there are few related documents and invention patents on fermented tea beverages, and there is no mention of unstable active ingredients such as catechins and low bioavailability in fermented tea beverages, and most of the production processes are carried out one by one. Tea extraction, fermentation and other links are relatively cumbersome

Abstract

The invention discloses a green tea fermented tea beverage and a preparation method thereof. The preparation method comprises the steps that green tea leaves are taken and smashed and are subjected to non-thermal sterilization, distilled water, saccharosephosphorylase, other complex enzymes, a carbon source,plant sourceoligopeptide, saccharomycetes and lactic acid bacteria are respectively added, a multi-process synchronized and integrated technology including low temperature digestion, enzymolysis, fermentation and the like is performed, the multi-process synchronized and integrated technology is finished after being completed, residue removal and filtration are performed to obtain green tea fermented tea juice, low temperature digestion of the tea leaves, glycosylation modification of catechin and brewing of nutrition and flavor of the fermented tea beverage are achieved at a time, the stability of the green tea fermented tea beverage is improved, the bitter taste of the product is decreased, the flavor quality of the beverage is improved, and the bioavailability of the catechin is improved. The method is simple and convenient to operate and obvious in effect and has a good popularization and application value and market prospect.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a green tea fermented tea beverage and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the in-depth research on the health function of tea, tea beverages developed from tea leaves are becoming more and more popular all over the world, and are deeply loved by consumers, among which green tea beverages are the most popular. The main technical difficulties in the processing and storage of tea beverages include: turbid precipitation of tea soup, browning of soup color, heavy bitterness and astringency of pure tea beverages, low bioavailability of active ingredients of tea, loss of aroma components, etc. At present, the research and application of key technologies related to tea beverage quality optimization have achieved certain results. Among them, there are many kinds of key technologies for the stabilization (precipitat...
